[VI-740] Establishment of tunnel construction method not dependent on worker's skill
Keywords:tunnel, high-flow concrete, computer-jumbo, productivity enhancement
In tunnel construction, in order to ensure safety, quality, processes, and benefits, there is a current situation relying on the ability and skill of workers.In the future, construction workers will continue to decrease and it will be very difficult to secure skilled workers.
We worked on the following three items in order to establish a tunnel construction method that does not depend on the skill level of workers.
(1) Adoption of high fluidity concrete for lining
(2) Adoption of five-person simultaneous call radio in face operation
(3) Adoption of computer jumbo (automatic boring guidance system) with tunnel supporting
